摘要
[目的]对三峡库区忠县向斜内部滑坡空间分布特征进行研究,为该区地质灾害防治工作的开展提供理论依据。[方法]在详细野外地质调查研究的基础上,应用构造地质学相关理论,以三峡库区忠县向斜为研究重点,对忠县向斜构造与滑坡分布特征之间的关系进行了深入研究。[结果]忠县向斜局部构造可以划分为3个区段,分别为北部忠县向斜与万县向斜复合区段、中部忠县向斜主体区段和南部忠县向斜与SN向构造复合区段。[结论]滑坡主要分布于北部和南部区段,主体区段滑坡规模较小;每个区段滑坡空间演化特征具有各自的特点,与局部构造特征改变相对应。
[Objective]The spatial distribution characteristics of landslides in the Zhong County syncline in the Three Gorges Reservoir area were studied in order to provide theoretical basis for the prevention and control of geological disasters in this area.[Methods]On the basis of detailed field geological investigation,this paper took the Zhongxian County syncline in the Three Gorges Reservoir Area as the research focus and made in-depth discussions on the relationship between Zhongxian County syncline and landslide distribution characteristics by applying relevant theories of structural geology.[Results]The local structure of Zhongxian County syncline can be divided into three sections:the composite section by Northern Zhongxian County syncline and Wanxian County syncline,the main section of Central Zhongxian County syncline,and the composite section by southern Zhongxian County syncline and SN trending structure.[Conclusion]The landslide is mainly distributed in the northern and southern sections,and the landslide scale of the main section is relatively small.The spatial evolution characteristics of landslide in each section are different correspondingly as local structural features change.
